BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 332,292, dated December15, 1885 Application filed May 21, 1885. Serial No. 166,225.

To all whom it may concern.-

Be it known that I, WILLIAM W. SEELEY, of the city and county of Albany,in the State of New York, have invented new and useful Improvements inBaling-Presses, of which the following is a specification.

My invention relates to the mechanism for operating the plungers ofbaling-presses; and it consists in constructing said operating mechanism in such manner that when the plunger of the press is at a point toproduce the greatest compression of the material in the press the pitmanconnection with the drivingwheels will be sufficiently released topermit the plunger to be forced back by the resilient action of thecompressed material.

In the accompanying drawings, which are herein referred to, and formpart of this specification, Figure 1 is aside elevation of a presscontaining my improvements; Fig. 2, a plan view of the same, and Fig. 3a longitudinal section at the line as x.

As shown in the drawings, A is the framework of the press, which is inthe usual form for procumbent presses; B, the feeding-hopper throughwhich the material is fed into the press-box. The driving-shaft O isprovided with a belt-pulley,c, for receiving powerfrom a steam-engine orother suitable motor. Said shaft is also provided with pinions c, whichare firmly secured thereto. The teeth of the pinions c engage in theteeth of the gearwheels D, which are fitted on their respective shafts din such manner that the said shafts may turn freely without impartingmotion to said wheels. Cranks E are secured to the inner ends of theshafts d, and are connected together by the crank-pin 6, so that the twocranks will move in unison. Snugs d are formed on the inner face of eachgear-wheel D, and are adapted to bear against the crank-pin end of thecranks E, but in such manner that any force moving in the same directionas the travel of the crank-pin 6, but at a higher rate of speed, willcause the crank-pin end of said cranks to break their contact with saidsnugs, and swing onward at an accelerated rate of speed until the forcecausing such accelerated movement is overcome. The pitman F is connectedby the head f to the crankpin e,

(No model.)

and by its opposite end to the reciprocating plunger G. ltatchet-wheelsH are secured to the outer end of the shafts d, and pawls I are adaptedto engage in the teeth of said ratchetwheels when occasion requires tosustain the weight of the cranks and that end of the pitman which isconnected thereto.

A vertically-reciprocating bar, J, is fitted in the lower part of therearmost end of the feeding-hopper B. Thesaidbaris preferably made inthe triangular form shown, with a sharp edge downward; but may be madeof a quadrangular form when preferred. Said bar is provided with atongue, j, at each end,

which tongues move in guides a, so as to constantly maintain the bar inits proper position. The purpose of the reciprocating bar J is to breakdown and retain the loose material at the upper side of each successivecharge that is forced into the pressing-chamber, and for this purpose Iconsider it essential that the said bar should be reciprocated with apositive motion, so that its movements can be arranged to occur at therequired times, and to this end a toggle-joint, j, is connected to eachend of the reciprocating bar J. The upper ends of said toggle-joints arepivoted to the feedinghopper, and their knuckles are connected by rodsjto the crosshead j which is reciprocated by arms is on the rocker-shaftK,and the latter derives its motion from a crank, L, which is secured toone of the shafts d, and is connected by the rodl to the arm 70 on saidrockershaft.

The operation of my press is as follows: The

successive charges of hay or other material are fed into thefeedinghopper B. The loose gear-wheels D are revolved in the directionindicated by arrows in Figs. 1 and 3. The

snugs d on said wheels engage with the cranks E, and force them to swingaround to force the plunger G rearwardly into the press to compress thematerial contained therein. The

at which point the weight of the cranks and pitman will be sustained bythe ratchet-Wheels H and pawls I, and the plunger Gwill remainstationary until the snugs d re-engage with the cranks E, to again movethem, as above described. After the rebound of the plunger G thefeeding-opening of the press-box will remain open for the introductionof the material until the plunger starts to move inwardly. While thecranks E are in motion the crank L partakes of their motion to operatethe reciprocating bar J, as hereinbefore described. When preferred, theratchet-wheel H and its pawl I on the shaft (1, on which the crank L issecured, may be dispensed with, and under such a condition the wheelD onthat side will be secured to the shaft d, from which the ratchet-Wheelhas been omitted, and the crank E will be fitted to turn loosely on andindependently of said shaft, and when so construced the power requiredfor operating the reciprocating bar J in breaking down the loosematerial at the upper side of each fresh charge will beindependent ofthe force of the rebound of the plunger, but will be derived directlyfrom the driving mechanism through the tight driving-Wheel.

I claim as my invention 1. In a baling-press, the combination, with thedriving-Wheels D, loosely fitted on the all arranged to rotate on thesame axial center line, with either one or both of said Wheels fitted toturn freely on the shafts d, the said wheels being provided with snugsd,which are adapted to engage with the cranks E,as herein described, ofthe reciprocating plunger G, connected by the pitman F to the cranks E,one or more ratchet-wheels,H,and a pawl or pawls, I, all constructed andarranged to operate as herein specified.

3. In a baling-press, the combination, with the gear-wheels D, shafts d,and cranks E, of the crank L, rocker-shaft K, toggle j oint j, andreciprocating bar J, all being connected and arranged tooperate asherein specified.
